CVE-2024-5633Public exploit

Full device access via unauthenticated memory writes

Published Jul 9, 2024 · Updated Aug 1, 2024

Hidden functionality in all LBH30FE200W-based cameras allows remote attackers to gain full device access through the CoolView service. The undocumented TCP service on port 8830 accepts unauthenticated opcode 0x61 memory reads and 0x62 memory writes to attacker-chosen addresses. Access requires the same local network and command knowledge; rewriting the /bin/login string removes the Telnet login barrier.
